[PATCH v2 0/9] ALSA: add virtio sound driver
by Anton Yakovlev 08 Feb '21

08 Feb '21

This series implements a driver part of the virtio sound device specification v8 [1]. The driver supports PCM playback and capture substreams, jack and channel map controls. A message-based transport is used to write/read PCM frames to/from a device. The series is based (and was actually tested) on Linus's master branch [2], on top of commit 1e2a199f6ccd ("Merge tag 'spi-fix-v5.11-rc4' of ...") As a device part was used OpenSynergy proprietary implementation. Any comments are very welcome. v1->v2 changes: 1. For some reason, in the previous patch series, several patches were squashed. Fixed this issue to make the review easier. 2. Added mst(a)redhat.com to the MAINTAINERS. 3. When creating virtqueues, now only the event virtqueue is disabled. It's enabled only after successful initialization of the device. 4. Added additional comments to the reset worker function: [2/9] virtio_card.c:virtsnd_reset_fn() 5. Added check that VIRTIO_F_VERSION_1 feature bit is set. 6. Added additional comments to the device removing function: [2/9] virtio_card.c:virtsnd_remove() 7. Added additional comments to the tx/rx interrupt handler: [5/9] virtio_pcm_msg.c:virtsnd_pcm_msg_complete() 8. Added additional comments to substream release wait function.

[PATCH] ASoC: SOF: debug: Fix a potential issue on string buffer termination
by Hui Wang 08 Feb '21

08 Feb '21

The function simple_write_to_buffer() doesn't add string termination at the end of buf, we need to add it on our own if calling that function to write the size of count chars to buf. This change refers to the function tokenize_input() in debug.c and the function sof_dfsentry_trace_filter_write() in trace.c. We didn't find this potential issue in the past because sometimes we are very lucky, we kzalloc the size of count buf, the kernel not only returns a buf with buf[0 ... (count - 1)] = 0 but buf[count] = 0, with this luck, this issue will not be exposed.

[PATCH 0/7] Add audio driver base on rpmsg on i.MX platform
by Shengjiu Wang 07 Feb '21

07 Feb '21

On Asymmetric multiprocessor, there is Cortex-A core and Cortex-M core, Linux is running on A core, RTOS is running on M core. The audio hardware device can be controlled by Cortex-M device, So audio playback/capture can be handled by M core. Rpmsg is the interface for sending and receiving msg to and from M core, that we can create a virtual sound on Cortex-A core side. A core will tell the Cortex-M core sound format/rate/channel, where is the data buffer, what is the period size, when to start, when to stop and when suspend or resume happen, each of this behavior there is defined rpmsg command. Especially we designed the low power audio case, that is to allocate a large buffer and fill the data, then Cortex-A core can go to sleep mode, Cortex-M core continue to play the sound, when the buffer is consumed, Cortex-M core will trigger the Cortex-A core to wakeup to fill data.

Hi folks. On 5.11-rc6 (git 3aaf0a27ffc2) I caught a new issue. For unknown reason sound disappeared in my headset Hyperx orbit s. But after reconnecting to another USB port headset stopped being detected as USB device in dmesg and in log appears a record about bug KASAN: use-after-free.

[PATCH] soundwire: debugfs: use controller id instead of link_id
by Srinivas Kandagatla 06 Feb '21

06 Feb '21

link_id can be zero and if we have multiple controller instances in a system like Qualcomm debugfs will end-up with duplicate namespace resulting in incorrect debugfs entries. Using id should give a unique debugfs directory entry and should fix below warning too. "debugfs: Directory 'master-0' with parent 'soundwire' already present!"
